Silsilat al-Ahadith al-Sahihah

Mu'abad Jahani says that Sayyiduna Mu'awiyah (may Allah be pleased with him) used to narrate fewer ahadith from the Messenger of Allah (peace and blessings of Allah be upon him), and he would rarely leave out these words (or the narrator said that) he used to mention them in the Friday sermons: The Noble Prophet (peace and blessings of Allah be upon him) said: "When Allah intends good for someone, He grants him understanding in the religion. Wealth is sweet, lush, and attractive; whoever acquires it rightfully, it will be blessed for him. And you people should avoid praising one another, for doing so is akin to slaughtering."
